| 摘 要： | 分析了开放网格体系结构（OGSA）的服务本质，论证了作为网格技术重要组成部分的网格服务调度服务对于服务质量（Qos）的需求，提出了一种基于QoS的网格调度随机高级Petri网模型，并对该模型进行了分解和精化，从而简化了模型的求解，以实现基于服务质量（QoS）的网格服务调度。

| Abstract: | Requirements of Quality of Service (QoS) of Grid system were continuously increased,with the rapid developments of Grid technologies.In this paper,the characteristic service of Open Grid System Architecture (OGSA) was analyzed,requirements of QoS of Grid service scheduling,which was the important part of Grid system,was given,then a scheduling model of Grid service based on QoS was constructed,the model was decomposed and reduced,solutions of the model were simplified to realized a scheduling of Grid service based on QoS. |

| Keywords: | Architecture Quality of service Scheduling of grid services Stochastic high-level petri net |
